Abstract

A kicker paddle is disclosed for use with a reclaiming drum. The kicker paddle may have a block with a first end and a second end. The kicker paddle may also have a mounting mechanism located between the first and second ends. The kicker paddle may be symmetric relative to a plane passing through the mounting mechanism that is parallel to the first and second ends.

Claims

1. A kicker paddle for a reclaiming drum, comprising:

a block having a first end and a second end; and

a mounting mechanism located between the first and second ends, the mounting mechanism including;

a first ear connected to an inner surface of the block; and

a second ear connected to the inner surface of the block and spaced apart from the first ear in a width direction of the block to receive a flighting of the reclaiming drum between the first and second ears,

wherein the kicker paddle is symmetric relative to a plane passing through the mounting mechanism that is parallel to the first and second ends.

2. The kicker paddle of claim 1, further including at least one fastener configured to pass through the first ear, the flighting, and the second ear to connect the kicker paddle to the flighting.

3. The kicker paddle of claim 2, wherein the block extends past the first and second ears in the width direction to provide protection to opposing ends of the at least one fastener.

4. The kicker paddle of claim 3, wherein the at least one fastener includes two fasteners spaced apart in a length direction of the block.

5. The kicker paddle of claim 3, wherein the block is generally rectangular and extends past the first and second ears in a length direction.

6. A cutting tool for a reclaiming drum, comprising:

a plate-like flighting configured to be connected to the reclaiming drum at a first end in general alignment with a rotational direction of the reclaiming drum;

a rectangular block removably connectable to a leading edge of the plate-like flighting in an orthogonal orientation relative to the rotational direction of the reclaiming drum, the rectangular block having a first end and a second end;

a mounting mechanism located between the first and second ends, wherein the rectangular block is symmetric relative to a plane passing through the mounting mechanism that is parallel to the first and second ends; and

a cutting bit operatively connected to a second end of the plate-like flighting opposite the reclaiming drum,

wherein the mounting mechanism includes;

first ear connected to an inner surface of the rectangular block; and

a second ear connected to the inner surface of the rectangular block and spaced apart from the first ear in a width direction of the rectangular block to receive the plate-like flighting between the first and second ears.

7. The cutting tool of claim 6, further including at least one fastener passing through the first ear, the flighting, and the second ear to connect the rectangular block to the plate-like flighting.

8. The cutting tool of claim 7, wherein the rectangular block extends past the first and second ears in the width direction to provide protection to opposing ends of the at least one fastener.

9. The cutting tool of claim 8, wherein the at least one fastener includes two fasteners spaced apart in a length direction of the rectangular block.

10. The cutting tool of claim 8, wherein the rectangular block extends past the first and second ears in a length direction.

11. The cutting tool of claim 6, wherein the rectangular block extends a distance away from the reclaiming drum to an edge of the cutting bit.

12. The cutting tool of claim 11, further including a tool mounting block operatively connected to the second end of the flighting, wherein the rectangular block extends away from the reclaiming drum past the tool mounting block.

13. A method of servicing a reclaiming drum, comprising:

removing at least one fastener that passes through a kicker paddle and a flighting;

detaching the kicker paddle from the flighting;

inverting the kicker paddle;

reattaching the kicker paddle to the flighting; and

reinserting the at least one fastener back through the kicker paddle and the flighting,

wherein removing the at least one fastener includes removing the at least one fastener from opposing flange ears of the kicker paddle that are located at opposing sides of the flighting and orthogonal to a rectangular block of the kicker paddle.

14. The method of claim 13, wherein removing and reinserting the at least one fastener includes removing and reinserting two fasteners, the two fasteners being aligned with each other in a length direction of the kicker paddle.

15. The method of claim 13, wherein removing the at least one fastener includes removing the at least one fastener from a protective pocket located between a flange and a block of the kicker paddle.

16. A reclaiming drum, comprising:

a head having a cylindrical outer surface;

a plurality of flightings separately welded at a first end to the reclaiming drum at spaced apart locations;

a tool mounting block fixedly connected to a second end of each of the plurality of flightings;

a cutting bit disposed within each tool mounting block;

a kicker paddle removably connected at a leading edge of each of the plurality of flightings; and

at least one fastener passing in an axial direction of the head through opposing flange ears of the kicker paddle and the corresponding one of the plurality of flightings,

wherein the flange ears are located at about a lengthwise mid-point of the kicker paddle.

17. The reclaiming drum of claim 16, wherein the kicker paddle includes a block disposed in an orthogonal orientation relative to the associated one of the plurality of flightings, the block extending in a width direction past the flange ears to create protective pockets for the at least one fastener.
